N identical cells, each of emf E and internal resistance r, are joined in series to form a closed circuit. One of the cell A is joined with reversed polarity. The potential difference across each cell except A is A) 2E/n B) (n-1)E/n C) (n-2)E/n D) 2nE/n-2?
Verified Answer
N identical cells, each of emf E and internal resistance r, are joined...
Number of cells= n

EMF of each cell= E

and internal resistance of each cell= r

Total resistance in circuit= nr

One cell is joined in reverse, so total emf = nE-2E

Current in the circuit, I= nE-2E /nr

 =E(n-2)/nr

Potential difference ,V = E- Ir

= E-(n-2)Exr /nxr

= E[1-(n-2)/n]

=2E/n
